Siemens 5SX2 204-8 Molded Case Circuit Breaker

Siemens 5SX2 204-8 Molded Case Circuit Breaker is a two-pole, molded-case protective device from Siemens' 5SX2 series, intended for protecting 230/400 VAC circuits in industrial power-distribution panels. The 204-8 designation identifies a 6 A nominal current rating for a 2-pole unit with a 230/400 VAC supply and a D-characteristic trip curve, which describes its thermal-magnetic trip behavior under overcurrent and brief overload conditions. This compact MCCB is designed for protection of feeders and light-to-moderate motor circuits within control panels and industrial electrical installations. As part of the 5SX2 family, it shares the same mounting and electrical footprint as other 2P variants, enabling straightforward replacements or substitutions in compatible Siemens panel lineups.
